Fast handover scheme based on enhanced access point (EAP) for Mobile IPv6

Mobile IPv6 has been proposed to support host mobility in the Internet, yet during a handover Mobile IPv6 (MIPv6) suffers from packet disruption and packet loss. Furthermore, inherent delays associated with movement detection are unavoidable in standard MIPv6. In this paper, we propose to mitigate such effects with a more efficient fast neighbor discovery routine which requires each access point to execute movement detection using an enhanced beacon signal with stored router advertisement (RA) messages; we also implement a modified access point to handle fast configuration of the care-of address (CoA). Performance analysis indicates the handover latency in the proposed scheme could be reduced compared to standard MIPv6. The proposed scheme is also a strong candidate to support real-time application like VoIP.
